Effects of SEP and TES-MEP on the operation success rate and safety of patients with spinal surgery / 局解手术学杂志

ABSTRACT

Objective To investigate the success rate and safety of transcranial electrical stimulation motor evoked potentials (TES-MEP) and somatosensory evoked potential(SEP) in the monitor of the spinal operation.Methods A total of 98 patients with spinal surgery in our hospital from December 2015 to December 2016 were selected and divided into observation group and control group according to the intraoperative monitoring method,49 cases in each group.SEP conbined with TES-MEP were used in the observation group,and SEP monitoring was used in the control group.Intravenous anesthesia was used in all patients to observe and record the amplitude and latency of SEP and TES-MEP.The results of the two groups were compared with those of the postoperative spinal motor and sensory function and the complications.Results The successful detection rate of the observation group and the control group were respectively 100％ and 91.84％,and the difference was statistically significant(P ＜ 0.05).The sensitivity,specificity and Youden index of the spinal cord movement were significantly higher in the observation group than those in the control group,the difference was not significant(P ＞ 0.05).In addition,the sensitivity,specificity and Youden index of the sensory function were higher than those in the control group,and the differences were statistically significant (P ＜ 0.05).There was no significant difference in postoperation complication between the two groups (P ＞ 0.05).Conclusion SEP combined with TES-MEP in monitoring function changes of the spine during spinal surgery on sensitivity and specificity are higher than the SEP monitoring,which can accurately reflect the function of the spine in the operation state,and provide a good reference for surgery.
